1.3MP color LCD with color calibration function
Dual analog/digital interfaces with a color calibration function. Its built-in luminance stabilizing system provides stability in luminance.


Medivisor Grayscale Calibration capability for DICOM Part 14 compliant grayscale presentation

Calibrates luminance and gamma to enable smooth grayscale display that is faithful to DICOM GSDF.

Calibration function to accurately adjust gamma, color temperature, and luminance
Medical image displays are commonly required to display grayscale according to the Grayscale Standard Display Function (GSDF) defined by DICOM Part 14. The calibration function creates the optimum conditions for a medical imaging display by adjusting luminance levels, color temperature, and grayscale characteristics to achieve DICOM GSDF compliant grayscale output.

Models supported: All ME/CCL Series models, except ME183L and CCL192 plus
Note: Calibration requires an optional calibration kit*

How it works
The calibration function corrects the driving level of the LUT (Look-up Table), a memory that specifies the LCD driving, and writes it in the LUT. In other words, calibration adjusts grayscale characteristics, color temperature (color displays only), and luminance.

The luminance for each driving level is corrected such that the resulting curve matches the DICOM GSDF achieving smooth grayscale output.

The luminance for each driving level is corrected such that the resulting curve match the DICOM GSDF and smooth grayscale is achieved.

Luminance stabilizing system λ-Sentinel for stable display of medical images Luminance stabilizing system λ-Sentinel for stable display of medical images
Automatically corrects and luminance fluctuation due to startup drift, temperature change, and aging to provide stable luminance.

Luminance stabilizing system to provides continuous stable display for medical images

A change in luminance affects gamma characteristics and therefore has adverse effects on diagnostic imaging. TOTOKU'smedical image displays are equipped with a luminance stabilizing system that automatically compensates for luminance changes due to startup drift, temperature change, and aging.

Luminance stabilizing system λ-Sentinel

λ-Sentinel II Luminance stabilizing system λ-Sentinel II

λ-Sentinel II consists of a luminance sensor and a luminance control circuit. The luminance sensor attached in front of the screen constantly monitors and accurately stabilizes luminance on the screen surface by sending feedback to the control circuit.

Newly developed luminance stabilizing system λ-Sentinel IILuminance sensor
  • With luminance fluctuation caused by the LCD module taken into account, highly accurate luminance control is achieved.
  • Actual luminance measurements including intermediate luminance are taken on the screen surface.
  • Build-in luminance sensor provided with i2 models enables even simpler calibration without attaching the calibration sensor.

Note: λ-Sentinel II module is built into the the ME/CCL Series i model displays. Other models are equipped with λ-Sentinel (TOTOKU's conventional system).

Simultaneous display of 1276 shades of gray Built-in 10bit LUT (Look-up Table) to reproduce beautiful grayscale
The built-in LUT selects the most appropriate 256 shades of gray (8bit) out of 1021 shades (10bit) to realize finer and smoother grayscale.

* A viewer software that supports TOTOKU's multi-shade display system is reguired for 11-bit simultaneous display.

Built-in LUT (Look-up Table) to reproduce beautiful grayscale and TOTOKU's technology for simultaneous display of multiple shades
General-purpose displays are capable of 256 shades of gray, but due to unevenness and grayscale discontinuity, they cannot reproduce and display the subtle shading difference required for medical image displays. TOTOKU's medical image displays display the most appropriate 256 shades (8bit) out of a maximum of 12241 shades of gray using the built-in LUT. This technology realizes much finer and smoother grayscale than possible with general-purpose displays.

Moreover, combining with a TOTOKU display customized conversion table with an integrated viewer, up to 2048 shades of gray can be provided to produce film-like images on the display.
